Where This Product Is Used
The Schneider Electric NSX160N is a fixed-mount molded case circuit breaker (MCCB) engineered for demanding industrial and commercial power distribution environments. Engineers and panel builders specify this model across a wide range of critical applications:
- Motor Control Centers (MCC): Provides reliable short-circuit and overload protection for motors up to 75kW at 400V AC.
- Industrial Distribution Panels: Used as a main or branch circuit breaker in factory switchboards, protecting downstream equipment from fault currents up to 50kA.
- Building Automation & HVAC Systems: Protects large HVAC compressors, chillers, and air handling units in commercial buildings.
- Machine Tool & CNC Equipment: Installed in machine tool control cabinets requiring compact, high-performance protection.
- Water Treatment & Pump Stations: Safeguards pump motors and control systems in municipal water infrastructure.
- Oil & Gas Auxiliary Panels: Deployed in upstream and downstream auxiliary distribution boards where robust fault interruption is mandatory.
- Data Center PDUs: Used in power distribution units requiring high breaking capacity in a compact footprint.

Why Engineers Specify This Model
- High Breaking Capacity in Compact Form: 50kA Icu at 415V AC delivers superior fault protection without requiring oversized enclosures — critical for space-constrained panel designs.
- 100% Service Breaking Capacity (Ics = Icu): The NSX160N maintains full rated breaking capacity after a fault event, eliminating the need for immediate replacement and reducing downtime.
- Modular Accessory Ecosystem: Compatible with Schneider’s full range of NSX accessories — auxiliary contacts, shunt trips, undervoltage releases, and rotary handles — enabling flexible system integration.
- Fixed Design Reliability: The fixed (non-withdrawable) configuration eliminates contact wear from racking operations, ideal for installations where the breaker remains permanently in circuit.
- Wide Voltage Range: Rated to 690V AC, making it suitable for both standard 400V and higher-voltage European and Asian industrial networks.
- Proven Global Track Record: Part of Schneider Electric’s Compact NSX platform — one of the most widely deployed MCCB families in industrial automation globally.

Application-Specific FAQ
Q: What is the difference between NSX160N, NSX160F, and NSX160H?
A: The suffix denotes breaking capacity. N = Normal (50kA), F = High (70kA), H = Very High (100kA) at 415V AC. Choose based on your prospective short-circuit current (PSCC) at the installation point.
Q: Can the NSX160N be used for motor protection?
A: Yes. When fitted with a TM-D trip unit, it provides both overload (thermal) and short-circuit (magnetic) protection suitable for direct-on-line (DOL) motor starters up to 75kW.
Q: Is the fixed version field-upgradeable to withdrawable?
A: No. Fixed and withdrawable (plug-in/drawout) versions use different chassis. Specify the correct mounting type at the time of order.
Q: What accessories are compatible with the NSX160N?
A: The full Compact NSX accessory range is compatible, including: OF/SD/SDE auxiliary contacts, MX shunt trip, MN undervoltage release, rotary handles, padlocking devices, and terminal shields.
Q: Does Konmask.com provide a certificate of conformity?
A: Yes. A Schneider Electric certificate of conformity (CoC) and test report can be provided upon request for project documentation purposes.
Q: What is the lead time for out-of-stock units?
A: Typical lead time from Schneider Electric authorized stock is 3–7 business days for standard variants. Contact us for expedited sourcing.
